8-BIT SINGLE-CHIP MICROCOMPUTER (WITH A/D CONVERTER)

DESCRIPTION

The µPD78C11A is a CMOS 8-bit microprocessor which can integrate 16-bit ALU, ROM, RAM, an A/D converter,

a multi-function timer/event counter, and a general-purpose serial interface into a single chip, then expand the

memory (ROM/RAM) up to 60K bytes externally. The µPD78C10A is a ROM-less product of the µPD78C11A, and can

directly address the external memory up to 64k bytes. The µPD78C12A is a product which has more built-in ROM

capacity than the µPD78C11A, and its memory (ROM/RAM) can be externally extended up to 56K bytes. The

µPD78C10A, µPD78C11A, and µPD78C12A operated at low power consumption, because they have a CMOS

construction. Also, they can hold data with low power consumption by using standby function.

On-chip PROM products, µPD78CP14 and µPD78CP18 which are ideal for evaluation or preproduction use during

system development, early start-up and short-run multiple-device production of application sets, are available.

FEATURES

Non (µPD78C10A)

• On-chip RAM : 256W × 8

• High-precision 8-bit A/D converter : 8 analog inputs

• General-purpose serial interface : Asynchronous, synchronous, I/O interface mode

• Multi-function 16-bit timer/event counter

• Two 8-bit timers

• I/O lines : 32 (µPD78C10A), 44 (µPD78C11A, 78C12A)

• Interrupt function (external - 3, internal - 8) : Non-maskable interrupt × 1, maskable interrupt × 10

• Standby function : HALT mode, hardware/software STOP mode

• Zero-cross detection function : (2 inputs)

• On-chip pull-up resistor (port A, B, C: µPD78C11A, 78C12A only) by mask option

Caution The µPD78C10A does not hava a mask option.
